Is this an XML document?

If so, you're using a DOCTYPE declaration for the SGML DTD for DocBook
4.1, not the XML DTD.

The DOCTYPE for the XML DTD, would be something like this:
 <!DOCTYPE book
   PUBLIC "-//OASIS//DTD DocBook XML V4.1//EN"
   "http://www.oasis-open.org/docbook/xml/4.1/docbookx.dtd"; []>

Note that
 - the PUBLIC ID has an XML differentiating it from the SGML variant
 - XML requires a SYSTEM ID (before the internal DTD subset)
 - "book" is lowercase, because XML is case sensitive, while SGML is
   case insensitive
